Typical Application of the Dynamic VLAN

Scenario:

In the office network Department A belongs to VLAN100. Several members of this

department often have the need to move within the whole office network. It is also

required to ensure the resource for other members of the department to access VLAN 100.

Assume one of the members is M, the MAC address of his PC is 00-03-0f-11-22-33, when

M moves to VLAN200 or VLAN300, the port connecting M is configured as Hybrid mode

and belongs to VLAN100 with untag mode. In this way, the data of VLAN100 will be

forwarded to the port connecting M, and implement the communication requirement in

VLAN100.
